Package version

ros-humble-turtlebot4-setup/jammy,now 1.0.4-1jammy.20240909.222719 arm64 [installed]

Expected behaviour

• Running the turtlebot4-setup command, in ROS setup, Bash Setup
• If the user sets a ROBOT_NAMESPACE incompatible with the Create3 base
• The interface should issue a warning (or disallow the action in the first place)

Actual behaviour

The namespace is set in the RPi but not in the Create3, no error displayed

Error messages

No response

To Reproduce

1. set a namespace such as /robot0-1
2. Save and apply
3. Connect to the Create3 base UI
4. The namespace is not set, setting it manually gives the error: Valid characters for the namespace are ASCII letters from a to z, the digits from 0 to 9, and the underscore

Other notes

Since TB4 is marketed for education, even though this limitation does not depend on this platform, it should be clear that the namespace was not set correctly.
